MILK-BOTTLE CLOSURE CAP.

Application filed April 18, 1922. Serial No. 555,481.

To all whom it may concern Be it known that GERTRUDE E. BALL, citizen of the United States of America, residing at 51 Sargeant St, Springfield, in the county of Hampden and State of Masssachusetts, has invented certain new and useful Improvements in Milk-Bottle Closure Caps, of which the following is a specification.

This invention relates to improvements in milk bottle closure caps and its leading object is to provide a paper or card board closure cap with a socket shaped to receive the tip of any finger and capable of being withdrawn from its normal sealing position by an upward movement of the linger tip inserted in the socket; the socket being designed so that the caps may be placed in close contact with each other, with the socketed portions nesting in each other.

lVith the above and other objects in View the invention consists in certain new and useful constructions, combinations, and arrangements of parts clearly described and clearly illustrated in the accompanying drawings, in which:

Fig. 1 is a vertical sectional view taken through a milk bottle neck equipped with the improved closure cap.

Fig. 2 is a top plan view thereof.

Fig. 3 is a side elevation of a stack of the cap, showing how the socketed portions nest in each other.

Fig. 4 is a transverse sectional view of a modified form.

Referring to the accompanying drawings illustrating the practical embodiment or" my invention A designates a milk bottle neck, which is provided with the usual seat B, on which the paper or card board closure cap is disposed.

The cap C is formed circular, in the usual manner and is composed of paper or cardboard or like material. The material of which the cap is composed must be capable of being slightly extended or drawn so as to provide a finger receiving socket D, preterably located at the center thereof, and having its major axis disposed on a slight slant or angle, and suitably curved to provide a concave wall portion d which is slightly curved under the body of the cap to provide an abutment or stop 6 against which the tip of the finger of the user may be placed in order to withdraw the cap from its normal sealing position. I

. As shown in F ig. 2 tne socket D tapers from its mouth to its lower end wall, which closes the socket against the admission of milk or other i'luid contained within the bottle. By this arrangement a large number of the caps may be piled in a stack or enclosed compactly in a single container tube.

The extruded or drawn socket forming portions of the closure cap may be formed in the cardboard sheet during its progress through the paper making machine, before it passes through its final drying and while it is still in a semiplastic shape, the conveying belt of the paper making machine being provided with holes or the like to receive the formed sheet before entering the drier. Or the extruded socket forming portions may be formed by means of a hot die acting under pressure upon stock rendered pliable by the absorption of moisture. A special adhesive may be employed in the making of the paper stock, so that it will more readily adapt itself to the outlines of the shaping or extruding dies employed.

Having described my invention 1 claim and desire to secure by Letters Patent 1. A milk bottle closure cap having an extruded finger receiving socket, one side of the socket sloping toward the other side of the socket and the other side of the socket being disposed under the body of the cap to provide a finger abutment.

2. A milk bottle closure cap having an extruded finger receiving socket tapering from its mouth to its inner end wall and having a sloping wall and a wall disposed under the body of the cap to provide a finger abutment, the caps being capable of being disposed on one another so that the sockets will nest in each other with the op posing faces of the caps in close contact with each other.
